Figs. 9, l0 and 11 show the method of connecting the attaching devices to the hull of a vessel.

In Figs. 1 to 5 inclusive, I have indicated at 20 a part of the hull of a diving bell,

such as shown in the patent above referred In the practice of my invention, the hull 20 adjacent to the observation lenses 22 is provided with an enlarged bearing portion 23 through which passes the usual rotary member or shaft 24, which extends into the diving bell and is packed as shown at 25, and through which, in the practice of my invention, is passed a rod 26, the inner end of which is packed as shown at '27 and provided with an angular end portion 28, whereby the samemay be rotated by a suitable wrench or crank, and the outer end of which is threaded as shown at 29. The above .named parts may be of the usual or any desired construction, and the end of the rotary member 24 is preferably provided with a. conical or'tapered aperture 30, the opposite side walls 'of which are provided with key recesses 31 which extend the full length of said aperture, as clearly shown in Fig. 4.

The enlarged portion 23 of the hull is provided at one side of the rotary member 24 with an outwardly directed bearing 32 in which is rotatably mounted a shaft 33, the inner end portion of which is packed as shown at 34, and mounted on the inner end portion of said shaft and within the diving bell is a nut 35 having an enlarged base flange 36 provided with a plurality of apertures 37 arranged in pairs as shown in Fig. 3, and a headed pin 38 is adapted to operate in connection with the apertures 37- in the flange 36, and an aperture 39 in the hull, or the enlarged portion 23 thereof. The inner end of the shaft 33 is made angular in form as shown at 40 whereby a wrench, crank or similar device maybe connected therewith for rotating the'same.

The outer end of the shaft 33 protrudes beyond the bearings 32 and secured to the protruding end thereof is a tool and workpiece carrying member 41, comprising inner and outer disks 42 and 43 connected centrally by a hub portion 44 riveted to said disks, and by rivets 45 as clearly shown in Figs. 1 and 2 of the drawing,

The inner and outer disks 42 and. 43 are provided with a plurality of corresponding apertures 46 which are in common alinement, as clearly indicated in Figs. 1, 2 and 4, and these apertures are adapted to receive and support various tools and workpieces, and in Fig. 6 of the drawing I have shown a drill 47 provided centrally with an enlarged flange or collar48, and at its inner end with a tapered head 49 spaced from the collar 48 by a reduced neck 50, and the tapered head 49 is provided on opposite sides with longitudinal flanges or keys- 51 which are adapted to operate in connection with the key recesses 31 in the conical or tapered aperture 30, in the end of the rotary memher, and the'inner face of the head portion 49 is provided with a threaded aperture 52 adapted toreceive the threaded end 29 of the rod 26 as clearly shown in Fig.2 of the drawing,

I also employ a tap 53 having a central enlarged flange or collar 54 andan inner tapered head member 55 proVided with keys 56. The head member 55 is connected with the collar 54 by a reduced neck portion 57, and'the inner e'nd of the head member 55 is provided with a threaded aperture 58 adapted to receive the threaded end 29 of the rod 26.

In Fig. 8 I have shown one of a number of attaching devices 59, one end of which is threaded as shown at 60, and the other end provided with a tapered head member 61 provided with opposite side keys 62, and centrally thereof with an enlarged flangeor collar 63 connected with the head member -61 by a reduced neck portion 64, and the end and this method of supporting the drill, tap

and attaching devices prevents their displacement or disengagement from the carrying member 41, but in Fig. 1 of the drawing and as in Fig. 2 the dn 1 47 is shown in engagement with the rotary member 24 and supported centrally of the apertures 46, and the method of attaching the drill, tap and attaching devices with the rotary member, as indicated in Fig. 2, is accomplished in the following manner.

In Fig. 5, as above stated, I have shown the drill 47 in its normal position, or supported by the cariying member 41 which is the position of the tap and attaching devices shown in Fig. 1, and said tools and attaching devices are so supported that the tapered heads thereof clear the outer end portion of the rotary member 24, as clearly shown in Fig. 5, and when it is desired to drill a hole into the hull of a vessel as shown at 66 in Fig. 9, the carrying member 41 is rotated by turning the shaft 83, as above set out, to bring the drill 47 supported in the apertures 46 in the inner and outer disks of said member in line with the rotary member 24 after which the headed pin 38 is placed in position to lock said parts against movement, after which the rotary member 24 and rod 26 are moved outwardly and said rod rotated by means of a crank, as above set out, to secure the head member 49 of the drill in engagement with said rotary member, and this position of the parts is indicated in dotted lines in Fig. 5, and in accomplishing this result it will be noted that the drill 47 is held against outward movement by the engagement of the outer face of 85 the head portion 49 with the walls of the aperture 46 in the inner disk 42 as is evident on a consideration of Fig. 5 of the drawing. When the drill is connected, or

pin is again placed in position to lock the parts against movement and therotary 24 carrying the drill 47 is moved outw-ardl through the carrying member 41 as indicated in full and dotted lines in Fig. 2 of the drawing, and the hole 66 is drilled in the hull. I have not shown the means for moving the. rotary member 24 outwardly nor the means -for rotating the same for the reason that my invention is not limited to. this feature, and it may be the same as the means employed in the patent above referred to, or as usually employed in apparatus of this class.

After the hole 66 has been drilled in the above manner, the rotary member is moved inwardly and the above opemtion of attaching the drill therewith is reversed to again place said drill in the osition shown in Fig. 50f the drawing, a r which the carrying member 41 is rotated to bring the tap 53 in position to be connected with the rotary member, and said tap is operated to thread the aperture 66 in the hull, as shown at 67 in Fig. 10,'and afterward the tap is replaced in the carrying member in the manner of replacing the. drill, and the'carrying member 41 is again manipulated to bring one of the attaching devices 59 into position to be connected with the rotary member 24, and said member is operated to secure said device to the threaded aperture 67, as shown at 68 in Fig. 11 of the drawing,

Heretofore in order to accomplish the above described operations a drill is first connected with the diving bell when above water and said bell is dropped or moved downwardly into the water and held in engagement with the vessel by the magnets 21 and a hole is drilled in the hull by said drill,

. the desired result, while with my improvement the diving bell may be heldin engagement with the hull of a vessel in the desired position by the magnets 21, and when in such position a hole may be first drilled in the hull, and then said hole threaded and the 1 attaching device connected with the threaded hole without moving the diving bell from such position, furthermore the diving bell may be moved around the hull by the usual propeller mechanism employed, which mechanism is not shown, and a plurality of attaching devices may be connected with the hull without raising said diving bell to the. surface of the Water, and with the construction shown in Fig. 1, five of these attaching devices may be connected with the hull, but it will be understood that the carrying member 41 may be so constructed as to support any number of attaching devices or tools of various kinds and classes, the chief feature of my invention being the provision of means for supporting tools and attaching de vices and for bringing them into position to be engaged and sup-ported by a rotary member operated from within the divin r bell.

While I have shown and descri ed certaindetails of construction for carrying my invention into efi'ect, it will be understood that my invention is not limited to such details, and changes therein and modifications thereof may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
